Brake question

[mjbjr25]

So i replaced my right caliper and pads today. Got it all back together with no "spare parts" left out. I bled the brakes and got the pedal nice and tight and test drove it. Stops good and no more pulling(The OEM caliper was stuck). Now I have a very very slight tugg or vibration type feel when I turn right. doent do it while turning left or driving straight. Did i over tighten something or not have something properly aligned?

When you were working on the brakes did you at any time turn the wheels/steering knuckles with the engine not running?

 

[mjbjr25]

Yes I did. In order to get a better angle or get the hose to reach

Ahhh, that's what I thought. Not a big deal, you sucked air into the rack. Drive around in an empty parking lot making slow figure 8's to purge the air out, and send me a nickle.

Thanks for the help. that did fix it. But seems I created a new problem. Once i hit about 60 I get a violent shake throughout the vehicle. If I stay below 60 it drives fine. Any ideas?

Sounds kind of like something is not aligned perfectly, and doesn't cause issues until you're going fast enough (60) for the vibrations to be noticeable?

 

[koda2000]

Did it vibrate before you replaced the calipers? Vibration around 60 MPH is usually a tire balance issue.

No vibration before. This shaking is more than a tire balance I believe. It shakes violently the entire truck. Could air be in the power steering line causing this?

Unless the ground is covered in snow, easy enough to try. I'd say 90% of the members here have turned the wheels with the engine off causing aerated P/S fluid with sometimes VIOLENT shaking. Give it a try when you can, usually takes only minutes before it subsides. GL

BTW Phil, I think you called it once again, but you spelled NICKEL wrong. So much for perfection huh? LOL

Put a little steering fluid in and then went to the grocery store and did the figure 8's and then to the school parking lot for more then a few minutes of circles back and forth and then to the interstate. Went up and down 4 times and kept it at 75 for 3 passes and 65-70 for the last pass. Seems all is fixed. I will test it again later today and tomorrow just to make sure. Thanks everyone for your help. I do appreciate it.

Yes, though it's more common when turning. Back to the figure 8's. Be sure to turn the steering wheel to full lock when doing this and do it at least 6-8 times.

Another possibility is that the wheel isn't sitting flat on the rotor/hub when replaced. Sometimes this can me due to rust/dirt on the back side of the wheel or the front side of the rotor. I've had wheels go on a bit crooked (usually on the rear axle stub) due to rust on the axle stub, which causes a tight fit on the center hole on alloy wheels.
